Specifically, we will introduce the following three categories:
(1) Regional alarm system（fire safety panel）: suitable for protected objects that only require alarms and do not require linkage with automatic fire equipment.
(2) Centralized alarm system（fire safety panel）: suitable for protecting objects that not only require alarm but also require linkage with automatic fire equipment, and only one fire alarm controller with centralized control function and fire linkage controller are set up; And a fire control room should be set up for the protected object.
(3) Control center alarm system（fire safety panel）: suitable for setting up protection objects for two or more fire control rooms, or protection objects for which two or more centralized alarm systems have been set up.
